I feel like a failure😢

My child’s father is a cheater. Always has been. When we broke up bc of his ways I promised myself I’d never go back but 2.5 years and a few hookups later here I am pregnant and expecting our baby in 5 months… he told me he changed and wanted to get back together for our family. I wanted to quit my job bc of how sick I was during the first trimester and he told me it was fine, “don’t worry kick your feet up” and he’ll take care of things financially so I did. He’s still been cheating and we’re about to lose our apartment bc our landlords are not lenient on being a month behind from that month I quit my job. I have the option to take my things and go stay with a family member till I get on my feet or follow him to a new place with cheaper rent and better landlords. I don’t want to leave him but I feel it’s best bc he’s still cheating and I simply just don’t trust him. It would be best for my mental health I think, but I just can’t bring myself to leave him. I feel so stupid and like im already failing the first test as a mother. I’m broke, unemployed, pretty much single and putting up with bs out of a man. Trying not to hate myself… but I kind of do. Trying not to regret my baby… but I kind of do I just wish the timing was better or that I was stronger. What does one even do in this situation…..
